ClassCastException casting to a OracleConnection in Jdeveloper

Question

Hi all,
Figured somebody on the list may know the answer to this one. Sounds to me like configuration step that I am missing.
I am running jdev 9031
I get a
java.lang.ClassCastException: com.evermind.sql.OrclCMTConnection
at tv.thirdspace.ova.debug.QueryTag.doEndTag(QueryTag.java:132)
at jsps.debug._debug._jspService(debug.jsp:24)
at oracle.jsp.runtime.HttpJsp.service(HttpJsp.java:139)
at run time when I execute a jsp tag lib.
I am doing the following in the tag lib
try {
Context env = (Context) new InitialContext().lookup("java:comp/env");
ds = (DataSource) env.lookup("jdbc/TestConnectionPool");
}catch (NamingException e) {System.out.println(e.getMessage());}
conn = (OracleConnection)ds.getConnection();
It is failing when I attempt to cast the connection as a OracleConnection.
The data-sources.xml has the following datasource definition
<data-source
class="com.evermind.sql.DriverManagerDataSource"
name="TestConnectionPool"
location="jdbc/TestConnectionPool"
xa-location="jdbc/xa/OracleXADS"
ejb-location="jdbc/TestConnectionPool"
connection-driver="oracle.jdbc.driver.OracleDriver"
username="scott"
password="tiger"
url="jdbc:oracle:thin:@infinity:1521:test"
inactivity-timeout="30"
/>     
What am I missing??

In the current version there is a restriction that you can only really have one (diagrammed) Struts configuration per project, as such we disable the option to create a new pageflow in the New gallery. What may be happening is that we're not recognising the fact that the existing xml file is a struts config (maybe the <!DOCTYPE > is wrong / missing? ) so we allow you to add a second and that messes things up.
